Bhubaneswar, July 12 - A band of Maoists ransacked a forest office located inside the Sunabeda wildlife sanctuary in Orissa's Nuapada district and destroyed all government records, police said Sunday.

'About ten rebels attacked the forest beat house at Sosenga revenue village, some 70 km from here (the district headquarters of Nuapada) late Saturday night, and destroyed all the official records,' district Superintendent of Police Bibek Rath told IANS.

He said the Maoists broke the gate of the beat house to enter it. No official was present in the building at that time.

The Sunabeda sanctuary, which is close to the border with neighbouring Chhattisgarh state, spreads over 600 sq km.

Maoists last month attacked another forest office in the same sanctuary and burnt government records.
